UNITED STATES PATENT OFFICE HAROLD I. BARDWELL, OF ROCHESTER, NEW YORK, ASSIGNOR TO ELECTROMATIC TYPEWRITERS, INCL, OF ROCKESTER, 'NEW YORK, A CORPORATION OF NEW YORK MOTOR MOUN TIN G v Application filed March 27, 1926, Serial No. 97,995. Benewed January 13, 1930.

- The object of this invention is to provide a simple, convenient and compact arrangement for mounting an electric motor upon and within the frame of a machine, such as a typewriter, which is to be actuated by such motor.

A typewriter is usually provided with y a box-like frame, and where the typewriter is to be provided with power-driven mechanism, it is desirable to mount the motor at the lower part of the frame and to conceal and house the motor as far as possible within the frame. At the same time, it is desirable to leave the motor open, so far as may be, for ventilation, and to minimize the weight of the structure. In accordance with the present invention, it is proposed to provide the motor with a frame,

1 this frame having at one end a late which is tor projects inwar attached removably to, and 18 preferably flush with, one of the flat plate-like members of the frame ofthe typewriter or other'machine. From this plate the frame of the moly into the space circumscribed by the machine frame, all parts of the motor being located within the plate so as to as i be enclosed or housed by the machine frame. Since the motor is so protected, it is not necessaryto provide the motor with a distinct housin or enclosure in its own structure, and the weight of the motor may thus be considerably reduced, while the workin parts of the motor are left open for the circu ation of air.

In the accompanying drawings, F ig. 1 is a sectional side elevation of a structure ineluding an electric motor and a portion of the frame, of a machine on which the motor'is mounted in accordance with the present -invention. Fig. 2 is a rear elevation of the parts shown in Fig. 1. v

The invention is illustrated as embodied in a machine, such as a typewriter, having a frame which comprises, at the bottom, .a vertical side plate 5' and rear plate 6. These lower parts of the frame may support one or Through the engagement of the Worm with a gear 11, the motor may drive a power shaft 12 through which the mechanism of the machine is actuated.v

The field core 14 of the motor is mounted on a frame 15 in which the armature shaft has its bearings. This frame projects rigidly from an end plate 16 at the rear end of the motor. The back frame member 6 of the machine is provided with a recess in which the -may therefore be of light construction and open for free circulation of air through its structure.

The invention claimed is: V The combination, with the frame of a powend plate is seated, and the plate is secured to the frame by means of screws 17. This coner-driven machine, said frame having side walls forming a box-like structure, with an opening through, one such wall; of an electric motor comprising: a verticalend-plate rej movably fixed to said wall and closing said opening therein, an 0 on frame fixed to and projectlng'inwardl rom said plate afield magnet supported y said frame, an an armature journalled on said frame, with its axis normal to the end-plate; the operative parts of the motor being enclosed entirely within said late and walls.

The motor is shown as comprising anare I mature 8, and the armature shaft is connected, by a coupling 9,'with a worm shaft ,10 mounted in bearings .13 on the frame
